flight sim upgrade

[MG44]

Am part of my local ATC Squadron and we have a rather old flight sim that am currently updating.
The PC is
AMD XP 2.2 GHZ
2GB DDR RAM
250W PSU
NVIDIA 5200 128mb AGP
we have a set of flight controls and a arvionces stack from elite hardwear

am woudering wot a gd up grade would be to run FS2004 with potential to look at FSX in the near future
we are geting some funding soon so will be running 2 19" tft monitors and possibly 2 more in the futre as well
how easy is it to transferre over our olod hard drive as it has all the data for our flight controls which will b a rite buggger to install on a new HDD as the company that makes it will want more money for a reinstall.
please can i have some surgestions!!!

Thank you

probbaly around the £400 to 500 mark
i want it to last for some time was thinking a a dual core would b gd
il build it myself unless a prebuilt is cheaper from some place
on the more than 2 screens front would a 4 output dvi card b a gd idea, assuming that the 4850x2 n 4870x2 will drop in price once the new range of cards r out

thanks

we r running FS 2004 currently and we had a ati 9800 pro until last week when i fried it(woops)
looking to get an ATI 1650 XT 512mb as it will run with current PSU
thats if we dont go 4 the complet rebuild as wasting money on an old agp single core seems silly
